I’ve been experiencing the same problem and goinf through the same routines to fix it. Created a new API Key, Copied it to General Settings under GCAL, vertified the calendar ID (email Address) from Google Calendar, redid the shortcode to reflect the ID in the feed listings.
The message has changed a bit over time; now it reads, “Some data was retrieved, but could not be parsed successfully. Please ensure your feed settings are correct.” The message is the same on the calendar grid and in the sidebar widget.
The site is floridasoutherngospel.org Pretty much the sole reason for the site is to offer a regional calendar of events for viewers. Dead in the water now for almost 2 months.
Thanks!
